Issue with RMR or is this normal?
I just purchased a new rmr with 1moa dot for my AR. As soon as I get home I mount it on the rifle and take it outside to view through the new optic. I realized when I stood out in broad daylight aiming into a dark area such as a garage, woods, or dark object, there appears to be a faded red pixelated rectangle surrounding the dot and obscuring targets. It does not go away except when walking back into a dim lit area, or I found when I cup my hand over the rmr it disappears. Adjusting the brightness doesn't make any difference it still remains there, and when it's turned completely off you can still see the minor outline of the rectangle. I had two other people look through to confirm I was not just seeing things. has anyone experienced this or heard of this?
